ZHCSIM2D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The digital audio data can be interfaced in either slave or master mode. The interface mode is selected by using the serial mode control described in the Section 7.4.2 section. The default mode is slave mode. Master mode is available only for ADC standalone operation by setting Register 6Fh/MPCSEL. In slave mode, BCK and LRCK are inputs to the ADC. BCK must be 64fS. DOUT changes on the falling edge of BCK. The default timing specification is shown in Figure 7-5. Section 6.8 lists the timing descriptions.
In master mode, BCK and LRCK are output from the ADC of PCM9211. BCK and LRCK are generated by the internal ADC from SCKI, and BCK is fixed as 64fS. DOUT changes on the falling edge of BCK. The detailed timing specification is shown in Figure 7-6. Section 6.8 lists the timing descriptions.
